Abstract

Eritrichium sericeum (Boraginaceae) callus and root cultures were established and analyzed for caffeic acid metabolite (CAM) production. Two substances, (-)-rabdosiin and rosmarinic acid, were identified as main CAMs produced by these cultures. The E. sericeum Er-1 root culture accumulated up to 1.5 % and 4.5 % DW of (-)-rabdosiin and rosmarinic acid, respectively. Rabdosiin in the Lithospermum erythrorhizon callus cultures was produced exclusively as the (+)-enantiomer while in both Eritrichium cultures it occurred as the (-)-enantiomer. The E. sericeum Er-1 culture accumulated 3-fold higher levels of CAMs than the L. erythrorhizon culture. A new compound, named eritrichin, was isolated from the cultured E. sericeum cells. The structure of this compound was established as (2R)-3-(3,4-dihydroxyphenyl)-2-[4-(3,4-dihydroxyphenyl)-6,7-dihydroxy-2-naphthoyloxy]propanoic acid on the basis of spectral data.
